I never said it did. What's your point? I'm just emphasizing that humans have clearly evolved to have social constraints in face-to-face interactions that haven't evolved in async, remote interactions (which is unsurprising).
> That sounds a lot like heated face to face interactions
Except it's not, and that's my whole point. Yes, of course people can have heated face-to-face interactions, but it's undeniable that people can be a lot nastier, quick to judge, be belligerent, etc. in remote interactions vs. in-person. And it's not just social media. Louis CK has a great bit about how he can be a total asshole when driving in traffic in a way that would be completely unacceptable/insane if he did it in an elevator, https://www.youtube.com/watch?v=x8062QEFk5g . The same dynamic applies in online interactions.
Evolution does not have an intended purpose.
> I've found myself needing to disconnect from social media because it leads me to having negative feelings about people that I know I like
That sounds a lot like heated face to face interactions. I guess that's why they call it "social" media!
People can take responsibility for their feelings and actions. Or they can find a scapegoat like social media. There's a long human tradition of scapegoating, after all.
